TELEGRAPHIC SENDING DEVICE.

Specification of Letters Patent.

Patented June 19, 1906.

Application filed January 27, 1903. Ser al No. 140,718-

To all whom, it may concern..-

Be it known that I, ISIDOR Krrsnn, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Telegraphic Sending Devices, of which thefollowing is a specification.

In the drawings I have selected as the best method of explaining myinvention the adaptation thereof to a use which I now directlycontemplateto wit, the signaling from the various car-barns of astreet-railway system to the central ol'lice of such system. Theinformation which it is desired to convey in such systems may comprise,for instance, the following details: the number of a car which hasstarted or is about to start from a given barn, the number of theconductor in charge thereof, and the trip-number of the car.

As the reports from the various barns are made at short intervals andmay often occur simultaneously, the conveyance of this intel ligence bytelephone would require the presence at the central office of a numberof telephone operators to receive and record the niultitudinousmessages. If, on the other hand, ordinary telegraphic apparatus beemployed, even though the receiving element at the central office beautomatic, itis still necessary that at each barn there should be askilled telegraph operator capable of transmitting the messages.

The economical object of my invention is to provide a telegraphicapparatus having an automatic receiving element and having atransmitting or sending element, which, while it affords the necessaryvariety of signals, shall be so simple in its method of manipulation asto require no telegraphic skill what- Thus any ordinary workman who canread numbers is competent to transmit messages which will comprehend allthe required information.

As it may be desirable to employ an apparatus in conjunction with atelephone-line between the barn and the central station, (in order topermit verbal conversation, where the transmission of other than theordinary messages may be necessary,) I have shown and described thesystem so organized that a portion of the telephonic circuit is utilizedfor the telegraphic connection.

In order to avoid confusion in nomenclature between the elements of thetelephone system and those of the special or telegraphic system of myinvention, I shall designate the former by the usual terms, such astransmitter, receiver, &c., and the corresponding elements of the latterby the terms sender and recorder.

In the drawings, Figure 1 represents diagrammatically such a combinedsystem extending between a single car-barn and the main or centraloilice, it being understood that in practice a number of such systemswill be employed to connect with the various barns. Fig. 2 is a frontelevation of the sending apparatus, showing a movable member placed inalinement, the others in their normal positions. Fig. 3 is an enlargedhorizontal section through a portion of the board. Fig. 4 is a verticalsection through the sliding block.

In order to readily explain the general nature of the system shown inFig. 1, it will be convenient to ignore for the time being the detailsof the sender and recorder, simply understanding for present purposesthat the former is capable of electrically transmitting a plurality ofsuccessive signals of definite character by appropriate mechanism andthat the latter is capable of recording said signals, as, forinstance,upon a paper ribbon.

Referring now to Fig. 1, A indicates the group at the car-barn, and Bthe group at the central office, C C indicating the line-wires of themetallic telephone-circuit between the two points, and F the battery. Atthe group A the telephone is shown as ordinarily constructed, thetransmitter thereof being indicated at a, the receiver at a, and thespringhook for the latter at (L2. The contact-terminal for the hook inits released position is shown at a, the call-bell at a", and thecondenser for operating said bell at a.

At the other end of the line 1) indicates the telephone-receiver, I) thetransmitter, b the magnet of a relay whose armature b is adapted toclose a local circuit from a battery f, so as to energize a signal-lampb.

A magneto-electric machine f is provided for signaling to the other endof the line, an ordinary switching device to throw the same into and outof circuit being indicated at b. All these parts are representedconventionally,

and the system thus indicated may of course be varied in any desiredmanner.

From convenient points of the main telephone-circuit shunt-wires D leadat the respective ends of the line to the special or telegraphicapparatus characteristic of my invention, the sender of which isindicated by the group of elements at E and the recorder by the group atE. From the proper elements at each end of the line wires G G,respectively, lead to the ground.

A switch d may be provided, whereby the telegraphic system can be thrownout of circuit, if desired.

When the telephone-line is to be used as such, the removal of thereceiver a from its hook a permits the closing of the circuit at a andby means of the relay b gives the signal for telephone conversation bythe illumination of the lamp 5. Similarly, when it is desired totelephone from the central office at B to the barn at A, the magneto fbeing actuated, with its switch 6 in proper relation, the bell a will berung by reason of the action of the condenser (0 whereupon thetalking-circuit can be utilized in the ordinary way. It will beunderstood, however, that the above-described embodiment is only typicaland has thus been set forth because it represents an obvious andconvenient adjunct to the system.

Referring now to the special or telegraphic apparatus characteristic ofmy invention, its main elements are a sender and a recorder. The latterof these two may be an ordinary Morse instrument having a paper ribbon,which is kept constantly moving by clockwork or other convenient deviceand provided with an element capable of producing upon the paper markswhose length and relation to one another have a predeterminedsignificance and which are in accordance with the currents successivelytransmitted from the sender.

The details of the sender will now be described by reference to Fi s; 2,3, and 4, the instrument being adapte for the transmission of three setsor groups of signals.

K is the base-board upon which the sending instrument is mounted.

L, L, and L are stationary conducting members secured to the base-board,each of these members being provided with raised portions representingpredetermined and definite words, as designated at M, whichraisedportions I call bars, and at the right of each of these membersare arranged a certain number of movable conducting members N, each ofthese movable members being also provided with raised portions which maybe conveniently described as dots and dashes, the dot beingapproximately onehalf the length of the dash and the dash, say, one-halfthe length of the shortest bar upon the stationary members. The dotsrange in value from one to five, designating the numerals 1, 2, 3, 4,and 5, and the dashes range in value from six to ten, designated by thenumerals 6, 7, 8, 9, and O but whereas the raised portions on thestationary members are arranged in one line each group of raisedportions designating a numeral on the movable members is given aseparate line thereon.

The movable members are guided in suit able guideways, as represented atO, and are normally held upward by springs or weights P.

Arranged upon the base-board K, directly beneath each of the movablemembers N, are pins or hooks Q, in number equal to the number of groupsof raised portions on the member N, each group designating one of thenumerals O to 9, inclusive.

R represents connections extending from the movable members andterminating with an eyelet or other means to be secured to one of thepins or hooks Q, so as to hold the member in proper operating position.

The bars M on the surface of the stationary members L, L, and L arearranged in a straight line with one another.

S is a traveling contact or block carrying a contact-sprin S, designedto come in contact with the ars M and also with one of the contactgroups upon the movable members when said movable members are arrangedin such a position that the contact roup will come in alinement with thepath 0 travel of the contact-spring S. The block S is guided in itsmovements by the rails or tracks T, and thus it will be seen that byraising or lowering any of the contact members N any line of contactgroups upon each of these movable members may be made to come intocontact with the contact-spring S, and as each line of contacts uponthese movable members represent a different numeral an combinationofnumbers can be made by t e proper masleeve W will slide upon the arm Uand the block will be actuated between the rails T.

When the sender is to be operated, the arm is pulled toward theleft-hand side of the instiument to the position as shown in Fig.2. Thenas the arm is released the spring Vwill act to force the arm toward theright-hand side of the machine, and the contact-spring S will pass overthe bars and contact groups in alinement with said bars.

To the binding-post Y is connected the terminal of the wire D. Anelectrical contact between said binding-post and the conducting-arm U isafforded by means of the switch-piece Y, adapted to bear with one endagainst one of the surfaces of the lower portion of the arm U. When thearm U is swung to the left-hand side, as illustrated in Fig. 2, thefrictional engagement of the switch-piece Y with the lower surface ofthe arm will cause this switch-piece to follow the movement of this arm,thus throwing the lower portion out of contact with the terminal Y.Hence there is no electrical connection between said arm and saidterminal during the period of movement of the arm in said direction; butupon the return movement of the bar the frictional engagement with theswitch-piece Y will at once bring the lower part of said switch-pieceinto electrical contact with the binding-post Y and will maintain saidcontact during the whole period of movement of the arm U in thatdirection. It will thus be seen that when the arm U is in the firstinstance swung to the leit across the faces of the bars, dots, anddashes no circuit will be established; but on the re turn movement ofsaid arm a circuit will be established with the wire D during theperiods of contact between the contact-spring S and the bars, dots, anddashes then situ ated in the line which it traverses.

The bars, dots, and dashes having a predetermined significance, it isobvious that any signals within the range comprehended by the variousgroups upon the stationary as well as movable members can be transmittedand recorded. In the signal system the dots may stand. according tonumber, for the numerals 1, 2, 3, 4,and 5and the dashes for the numerals"6, 7, 8, "9, and 0.

As stated at the beginning of this specification, I have illustrated myinvention as more particularly adapted for the use of signaling betweenrailway-barns and their center. It is customary for the person in chargeof starting the cars on their respective routes to signal the number ofthe car, the number of the conductor in charge of said car, and thenumber of the run or trip of said car to the superintendent at thecentral office. As an illustration, let us suppose that the large bar Mdesignates the word car and the contact groups on each of the followingmovable members indicate one of the numerals 1, (l2, )7 ((3,7) ((4,7)((5,)7 ((6177 ((7,!) (8,7) (9,77 O, and let us suppose that the firstmovable member adjacent to said stationary member is pulled downward, sothat the group of contacts consisting of only one dash comes inalinement with said bar, as is illustrated in Fig. 2. Then it is obviousthat the spring S in traveling over this bar and dash will indicate atthe receiving-station that car No. 6 has just been sent out. The secondstationary member is provided with two bars which may designate the wordconductor, and therefore any of the numeral contact groups placed inalinement with said two bars will give the number of the conductor ofsaid car when the spring S travels over the same. The third stationarymember is provided with three bars, which may designate the word run ortrip, and therefore any of the numeral contact groups placed inalinement with these three bars will give the number of the run or tripof said car when the contact spring S travels over the same.

To manipulate the movable members so that the proper numeral should comein alinement with the proper word or bar, it is only necessary to pullthe member downward and secure the ring or other means on the hookhaving the desired numeral placed opposite thereto. The person who sendsthe message need therefore only have intelligence and skill sufficientto understand the numbers which correspond to the dots and dashes andthe proper places to secure the respective contact groups. It will thusbe seen that a telegraphic message comprising all the information withinthe necessary scope can be transmitted by a person who has no skill as atelegraph operator, since all that he has to do is to pull down theproper movable members and secure them in their respective places andthen move the contact-arm across the proper region.

As stated before, the recording apparatus may be of any of thewell-known types adapted to receive and record signals of the bars,dash, and dot character. Hence to avoid prolixity no detaileddescription of this element is given.

It is obvious that the different members, stationary as well as movable,have to be in electrical contactwith each other. So, also, is it obviousthat the base-board may consist of an insulating material; but shouldthe same consist of a conducting material the arm, as well as theswitch-piece and binding-post, should be insulated therefrom. vious thatthe different members should not only be in electrical contact with eachother, but should also be in electrical contact with the ground-wire G.
